Description

A device for adapted air collectors to create turbulent flows in combustion chambers.

The present invention relates to a device for air collectors adapted to create flows turbulent combustion chambers.

Air collectors adapted to take air of the outside atmosphere and supply it to the chambers of Combustion are well known in the prior art. These collectors have a number of ducts (commonly called guide channels) in number equal to the number of cylinders that have to receive air or an air / fuel mixture, depending on whether combustion chambers have a direct injection system of fuel or mixed air / fuel in the engine before the combustion chamber inlet via a supply valve  respective.

The flow of air, or of air mixed with fuel, injected is controlled by means of a system of regulation controlled by the accelerator pedal of the vehicle engine. Conventionally, the higher the power necessary, the larger the choke opening will be so that can inject a greater amount of air (or mixture of air / fuel) to the combustion chamber.

One of the problems of these systems conventional is that optimal flow regulation is not obtained supply to cylinders, especially at a low number of engine revolutions In addition, current systems do not ensure turbulent flows of the swirl type inside the chambers of combustion optimally.

Therefore, the object of the present invention is to provide an air supply system, or air / fuel,  which lacks the inconveniences explained above.

Therefore, the invention relates to a device for air collectors according to the characteristics peculiar features claimed in claim 1.

The present invention will be described in continued with reference to the accompanying drawings, which show  a non-limiting embodiment thereof, and in which:

Figure 7 is another general view of the flow divider device of figure 3.

Figure 8 represents some details of flow divider device of figure 3.

Figure 9 represents a choke whose rotation around an axis is achieved by means of a new rack mechanism

In figure 1, an air unit is shown with 10 and includes an air manifold 11 and a dividing device of flow 12 fixed to each other by means of respective tabs 11, 12a that support one another and jointly set by one plurality of bolts 13 (figure 1).

It will be appreciated that only the details Structural essentials for understanding this Invention will be described and numbered in the following description.

The air manifold 11 also includes, in a manner conventional, a duct 11b for the admission of outside air into the direction of the arrow F1, and a main body 11c wound in spiral (to increase air turbulence) according to the turns of a plurality of guide channels 14 whose number is equal to the number of combustion chambers (not shown). In this case, there are four guide channels, so that the air unit 10 is capable of feeding a four-cylinder engine (not shown).

As depicted in more detail in the Figures 3 to 7, the device 12 includes a main body 15 obtained, for example, by melting a light alloy, which, at its instead, it includes a plurality of guide channels 16 in equal number to the number of guide channels 14. Since, as mentioned previously, the tab 12a of the device 12 is fixed to the tab 11a of the air manifold 11, each guide channel 16 is held to consider as the continuation of the respective guide channel 14.

In addition to tab 12a, device 12 includes another tab 12b, arranged on the opposite side with respect to to the main body 15, which is adapted to fix the unit 10 to the cylinder head (not shown) of an engine. The main body 15 and the two tabs 12a, 12b are also preferably arranged in one piece.

As depicted in more detail in the Figures 3 and 5 to 8, each guide channel 16 has a baffle respective longitudinal 17. Each longitudinal baffle 17 is extends between the two tabs 12a and 12b and you also get preferably rigidly with the other elements of the device 12.

In addition, each baffle 17 divides longitudinally the respective guide channel 16 in two channels 18 and 19 having a substantially identical cross section.

Each channel 18, 19, as will be described with more detail below, has a different function (see more ahead).

While channel 19 has no choke element, channel 18 includes a choke respective 20 adapted to be rotated by a mechanism that will describe in more detail below (see below).

The outer surface of each guide channel 16 it is provided with a respective seat 21 adapted to accommodate a respective injector 22 (figures 3 to 5) fueled by gasoline by a fuel distribution system 22a (figure 5). Every seat 21 also communicates with the respective channel 16 by means of a hole 16a (figures 5, 6).

As depicted in Figures 4 and 5, the axis (a) of seat 21 (and therefore of injector 22) is inclined with respect to an axis (b) of longitudinal channel symmetry respective guide 16.

In addition, as shown in Figures 5 and 6, the seat 21 and the injector 22 are arranged astride the respective deflector 17. So that the GET jet of the injector 22 can be divided between the channels 18, 19, the deflector 17 is provided with a hole 23 in the position of the hole 16a of the seat 20 communicating with the channel of
guide 16.

With additional reference to Figure 8, you can see that between the choke 20 and the inner walls of the relative channel 19 there is still a halo 24 through which can continue to pass a certain amount of air from the collector of air 11, even when the choke 20 is in the position completely closed as shown in figure 8. As result of this, a certain amount of air always "clean" the channel 18 in which the choke 20 is housed so that the fuel particles that remain in the walls of this channel 18 continue to be supplied to the respective combustion chamber (not represented). This feature prevents the accumulation of a certain amount of fuel in the walls of channel 18 that could be the cause of undesirable effects on the chamber of combustion when choke 20 opens again when the driver requires a sudden increase in power by operating the accelerator pedal (not shown).

Advantageously, the choke 20 divides the air flow in channel 18, whose air does not supply the mixture of air / fuel with a swirling movement.

In addition, in order to obtain benefits optimal, halo 24 extends along the entire perimeter  of choke 20 and there should preferably be a "factor of coverage "(k) that varies between 0.83 and 0.9; the term" factor of coverage "means the relationship between the surface area of the choke 20 and the surface area of the cross section of channel 18.

The choke 20 is always up (with respect to the air flow direction of the air manifold 11 to the engine head) of hole 23 and hole 16a through from which the fuel is injected.

It has been experimentally discovered that each choke 20 must be mounted in a position near the respective hole 23. In practice, with the choke 20 closed (position represented in figure 8), its surface that look at the engine head must be arranged at a distance of between 2 and 5 mm, preferably 3 mm, of the nearest edge of the hole 23 that communicates the two channels 18, 19.

In other terms, as represented in the Figure 5, the distance D between the axis (c) of the choke 20 and the nearest edge of hole 23 should be between 2 and 5 mm, preferably 3 mm.

Among other things, it has also been discovered experimentally that, to avoid the unwanted effects of the mixture that passes from channel 18 to channel 19, the surface area of the hole should be between 230 and 270 mm2, and preferably not must exceed 250 mm2.

Again, all stranglers 20 are made turn by the same rack mechanism 30 (see figures 7 and 9 in particular).

In practice, as represented in the Figures 7 and 9, each choke 20 is fixed to a spindle respective 31 by means of two screws 32. Spindle 31 is supported by a pair of bearings 33, 34 (figure 9) and by a support element 35. Each support 33 is housed in a seat 33a arranged in the respective channel 18.

As shown in Figure 9 in particular, between the support 34 and the support element 35 there is a pinion 36 with straight teeth that permanently meshes with a rod rack 37. Each pinion 36 is in a respective box 38 which closes with a sheet 39 which in turn supports and curls in two tabs 40, 41 (figures 4 and 5) protruding from the outer surface of each guide channel 16.

With reference to figure 7, each sheet 39 It also includes two through holes 42, 43 that make it possible fix, by means of screws (not shown), the respective box 38 containing, as mentioned above, a pinion respective 36.

With additional reference to Figure 7, you can see that the rack rod 37 is moved in translation by a electric motor unit 50 in the directions represented by the double arrow F2 in order to open (or close) channels 18 by medium of the throttles 20, depending on the conditions of drive set by the driver via the pedal Accelerator (not shown) and an electronic control unit (not represented). The electronic control unit converts the signal received from the accelerator and supplies it to each choke 20. The rack rod 37 is also partially housed in the box 38.

In other words, the rack mechanism 30 produces the translational movement of the rack rod 37 in the directions represented by the double arrow F2. Given the teeth 37a (figure 9) of rack rod 37 mesh with the teeth 36a of the pinion 36, the translation of this rod of rack 37 causes spindle 31 to rotate around the shaft (c) (Figures 5, 9) which, as mentioned above, is supported by bearings 33, 34, support member 35 and the sheet 39.

It will be appreciated that, at low speeds, each channel 18 is completely closed by the respective choke 20, apart from Aura 24, which still allows the passage of a certain amount of cleaning air. However, when the driver you want to increase the power supplied by the engine, the mechanism 30 causes the throttles 20 to open in order to allow the introduction of a greater amount of air / gasoline mixture to combustion chambers

The zipper mechanism 30, and in particular the drive of the motor unit 40, is controlled and ordered by an electronic control unit (not shown).

The operation of the device 12 of the present invention can be easily deduced from the above description and, therefore, it will not be described in detail later.

In addition, the previous comments made with reference to a conventional injection plant apply, mutatis mutandis , to a direct injection engine (not shown), that is, when the gasoline, instead of being injected into the guide channel 16, is injected directly to the combustion chamber.

The advantages of the present device invention are as follows:

- better control of the inflows of air / fuel mixture (or air only in the case of injection direct) to the combustion chamber;

- achievement of optimal turbulence through the creation of whirlpools of the swirl type in the chamber of combustion;

- creation, at low speeds, of a flow channel cleaner including the choke, even when the latter is in its completely closed position; this avoids the accumulation of fuel particles in the channel provided with the choke, which very often are the cause of combustion incorrect when the driver requires a sudden increase in engine power;

- optimum opening / closing operation of the throttles as a result of the use of a mechanism of zipper.
